The largest solar telescope on Earth takes the most detailed image of a sunspot we’ve ever seen

Scientists have just published the most amazing and detailed image of a sunspot human beings have never seen.

The image, taken on January 28 by the Inouye solar telescope, shows magnetic structures as small as 20 kilometers on the surface of the sun, said Thomas Rimmele, associate director of NSF’s National Solar Observatory (NSO) at a Statement from the National Science Foundation. NSF built and operates the telescope that captured this image, which was released on December 3. The solar telescope is the largest dedicated to observing the sun.
